Just to double-check that all the glowing accounts of the sacrifices that the "greatest generation" made during World War II weren't just nostalgia-laced propaganda, I called my favorite 80-year old. Sure enough, she remembered the rationing of gasoline and butter, Victory Gardens and--this one is particularly hard to imagine--saving aluminum foil rather than tossing it after a use or two.

These thoughts came to mind after the Live Earth concerts and the MoveOn-sponsored candidates' debate on climate change, both last Saturday. At the concerts, performers urged us to . . . turn off the shower while we shaved our legs. Among the six "actions against the climate crisis" we were asked to pledge were changing four standard light bulbs in our home to compact fluorescents, buying energy-efficient appliances, shutting off energy-using equipment when not in use, and riding public transit or carpooling once a week.

Flicking off the light switch when I leave a room now counts as doing my part to avert a climate crisis? Isn't it great to live in a time when it's so easy to feel virtuous?
